Hi,
I am a 30 year old female, CRB checked as i work as a producer on photo-shoots for a London fashion company and work with children on a regular basis. I am 1 of 17 cousins so great with babies, toddlers and teens.
I live in Uxbridge and am available evenings and weekends.
I am happy to pop round and say Hi if you were interested in using my service ad hoc.
Me and my boyfriend are saving for a mortgage and looking for some extra savings.
Please do get in touch. 
I can supply references as well.
Olivia
